Application led November 16, 1922. Serial No. 601,429.

To all whom t may camera:

Be it known that I, DAVID J. DoRs'EY, a citizen of the United States, residing at Baton Rouge, in the parish of East vBaton Rouge, State vof Louisiana, have invented certain new and useful Im rovements in Scot Blowers, and I do here y declare the following lto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

l This invention 4relates to new and useful improvements in cleaning devicesand particularly to devicesl for removing soot and ther accumulations from boiler pipes and ues.

One object ofthe invention is to provide a device of this'character by means ofwhich hardened or. baked deposits, which are not subject to the effect of a simple removed.

Another object is to provide a device of this character wherein steam and a gritty comminuted material are delivered into the boiler lues or pipes, with the' result that the caked or hardened material` will be ground loose and blown from the flues, with the result that the lues will be restored to their normal efficiency, and the maximum eiciency and economy of fuel preserved.

Other objects and advantages will be apparent from thefollpwing description when taken in connection with the accompanying drawing.

In the drawing.

Figure l4 is a side elevation offra flue cleaner made in accordance with the invention.

Figure 2-r is a vertical longitudinal central sectional viewthrough the device.

Referring particularly to the accompanying drawing, 10 represents a blow-pipe adapted for insertion in a boiler tube or flue 11, and is provided with a collar 12 adaptedl to engage with and close the end of the ilue, to prevent back pressure or escape .of the soot, said collar bei g ad-l justable relative to the blow-pipe by means of the set screws 13. In'the upper side of the blow-pipe 10and intermediate the length thereof, is a. sand receiving` opening 14, while an air linlet o ening 15 is formed in the' pipe a short distance rearwardly of the openingr 14. Entending longitudinally into the rear end portion of the blow-pipe 10 is a steam or air injector nozzle 16, the tip ofwhich is disposed adjacent the rear edge of the opening 14, and forwardly of the air inlet opening 15, said nozzle having suitable connections 17, with a source of steam or air supply, not shown, and having the check valve 18 provided with the upwardly extending valve stem 19. The casing of the valve carries 'a bracket 20 on which is pivotally mounted the operating lever 21, said lever lbeing arranged in position to engage with the outer end of the stem` 19 to depress the same.

Clamped on the upper side of the pipe 10, and over the' opening 14, is a plate 22,

said plate havingan upwardly extending nipple 23 which communicates with the opening 14. Formed intermediate the length of the nipple 23 is an enlargement 24 horizontally through which is formed the slot-25, and slidable in this slot, transy lvers'ely of the nipple, is a plate valve 26,

pipe, and into the boilerue, with the result that the incrustation will be effectively loos-A ened and blown from the fine.

.The rear end ot the steam connection 17 is provided with a suitable handle 29, which4 is grasped by the operator to hold the device while in operation..and to guide the pipe 10 into and out of the boiler ilue.

vWhat is claimed is: i

In a soot blower, the combination withA the blow pipe having an opening in itsV upper side, of an arcuate plate disposed on the pipe in covering relation to said opening and having a central opening registering with the pipe opening, a nipple secured laround the opening of the plate and rising therefrom, a horizontal flange In testimony whereof, I. ax my signaon the h.upper eng4 of the nipple, a seond ture, in the presence of two Witnesses.
